Karpathy has been quiet on X recently, now I finally understand why. He's been prepping hard for the Anthropic interview!

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

Andrej Karpathy joining Anthropic is the biggest flex Anthropic could have hoped for.

10m views after 6h. Best hire ever.
